Abstract: SELF-LOCKING THREADED FASTENER                         ABSTRACT           A self-locking fastener combination is pro vided with a thread construction having a thread which deforms to securely lock when a set of male and female members are threaded together and which is reformed upon unthreading of the members to allow subsequent reuse thereof.  The female member is provided with a conventional thread while the male member has a special helical thread defined by leading and trailing flanks in which a portion of the leading flank diverges away from the leading flank of the fe-male member to produce a space between the threads at the male thread root.  A portion of the male thread root is truncated and is of lesser depth than the female thread such that part of the female thread crest firmly engages and is deformed by the trun-cated male thread root into the space adjacent such root when the members are threaded together.  The deformed female thread crest produces firm metal-to-metal contact between the members completely around several revolutions of the circumference of the threads in order to preclude lateral movement of one member relative to the other and resultant loosening of the fastener when subjected to vibration.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is an improved liquid filter in which contaminated liquid is pumped into an inlet chamber, through a filter element, into an outlet chamber and out of the filter through an outlet pipe.  The inlet and outlet chambers have compartments which hold compressed air.  When the filter element becomes clogged with contaminants, inlet and outlet valves are closed, sealing off the filter.  A vent valve is then opened to quickly exhaust the compressed air in the inlet air compartment.  This allows the compressed air in the outlet air compartment to energetically force liquid back through the filter element thereby dislodging the deposited contaminants. The compartments and a liquid column between them are sized so that a discharge of liquid from the inlet compartment during the venting thereof is prevented.  Both air compartments are kept full of air regardless of the internal filter pressure by continuously bleeding air into the inlet air compartment from excess air bleeds into the outlet compartment to assure sufficient backwashing air and air pressure under all operating con-ditions.  The filter has a tangential inlet nozzle which facilitates the removal of heavier contaminants before they reach the filter element.

Abstract: ABSTRACT OF THE DISCLOSURE A circuit for use in a multiphase regulated supply to provide regulation of the ripple current contained in the filtered d.c. output signal of the supply.  The supply regulates its output voltage and/or current by controlling the conduction time of the switching elements contained in the rectifier portion of the supply.  The switching element conduction time is controlled by controlling the generation of firing pulses to the switching elements as a function of an error control signal which is equal to a first error signal.  This signal is equal to the amount by which the actual value of said voltage and/or current deviates from a reference value of said parameter. when the ripple regulation circuit is included in the supply, a second error signal is generated which represents the deviation of the d.c. value of the ripple from a predetermined reference. Also included in the ripple regulation circuit is circuitry for selecting the error control signal as equal only to the larger amplitude one of the first and second error signals.  The supply therefore regulates only voltage and/or current until the ripple becomes excessive at which point the supply regulates only ripple.

Abstract: ADSORBENT FRACTIONATOR WITH AUTOMATIC CYCLE CONTROL            AND PROCESS                     ABSTRACT OF THE DISCLOSURE   A method and apparatus are provided for adsorbing water vapor from a mixture thereof with a second gas to reduce the water vapor concentration in the mixture to below a permissible maximum concentration. The advance of the moisture front in a sorbent bed during either adsorption or regeneration or both is detected by deter-mining the change in the moisture content of the sorbent as a function of the capacitance of a capacitor in which the sorbent is the dielectric.  During adsorption, capacitance must be observed by way of a capacitor at least at a point in the bed sufficiently far from the end of the bed to prevent effluent having a limiting maximum moisture content from leaving the bed. When the capacitance at that point has reached a predetermined value corresponding to a selected moisture content on the sorbent, the adsorption or regeneration cycle is discontinued.

Abstract: METHOD AND APPARATUS FOR ANALYSIS OF CORNEAL SHAPE                   Abstract of the Disclosure An analysis of the corneal shape through the com-bination of several keratometer measurements is disclosed. The eye is preferably scanned to a nasal angular position,  a central angular position and a temporal angular position. The central position is straight ahead along the patient's line of sight.  The temporal and nasal positions are in the broad range of up to 5 to 22°; the intermediate range of 10 to 15°; and the narrow range of 12 to 14° on either side. Measurements in sphere, cylinder and axes are taken.  Astig-matism is in the more preferable format of 0-90° astigmatism and 45-135° astigmatism.  When each individual point is measured with its respective estimate for sphere and cylinder components, these measurements are fitted to an idealized parameter.  Then the three sets of curvature measurements taken at the specified locations are reduced to a set of adjusted, idealized curvatures all fitted to an elliptical model.  Thereafter, these fitted values create final corneal shaped parameters, the particular process here including the creation of intermediate parameters.  Finally, readings of central "k", corneal shape, apex position, cap size, vault height, corrected central "k" and goodness of fit are all set forth.

Abstract: METHOD AND APPARATUS OF CONSTRUCTING A  NOVEL UNDERGROUND IMPERVIOUS BARRIER                       ABSTRACT      A novel underground impervious barrier is construc-ted by excavating a trench or slot along the desired line of the impervious barrier in the presence of a bentonite slurry.  A double layered plastic film or sheet joined or folded at the bottom of the trench to form a sheath or envelope and open at the top and of sufficient verti-cal extent to extend above the ground and drape on both sides of the trench is installed in the trench and as the plastic sheath or envelope is installed in the trench it is hydraulically backfilled between the two facing surfaces thereof with a backfilling material having a greater density than the density of the bentonite slurry to sink the double layer plastic film or sheet to the bottom of the trench and displace the bentonite slurry forward in the trench toward the end being excavated. The impervious barrier constructed is constituted by the areas of the earth on the two facing side walls of the trench which are permeated by bentonite, each side wall having a bentonite cake contiguous thereto, a plastic membrane contiguous to the outer surface of the bentonite cake and the backfill material between the facing sur-faces of the plastic membrane.  Such a barrier is very useful for pollution control, for impounding water and/or otherwise effectively impeding horizontal flow of pollu-tants, water, oil and other flowable and/or substances leachable through the earth materials.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a method and an arrangment for giving send authorization to any of the terminals in a telecom-munication network, which are connected to each other through a common ring bus, controlled by a computer located at each of the terminals. On the ring bus a signal work frame of HDLC format circulates.  The frame which is sent from any of the terminals, comprises a send authorization word in the form of a specific signal pattern.  When one or more of the terminals con-nected to the bus is in a determined logic condition, that ter-minal receives the send authorization which is first to exhibit the logic condition in relation to the position of the send author-ization frame on the loop.  As soon as one of the terminals has received the send authorization it transmits an abort pattern within the frame to the bus.  The frame then becomes invalid and no other terminal can accept the send authorization.  When a ter-minal has completed its data transmission it retransmits the send authorization frame to the bus so that send authorization again is available to all the terminals.  When a terminal has nothing to send the terminal is aborted, and the circulating send permission is looped through the terminal back to the ring bus.          An address comparison logic circuit receives all the frames on a first input and compares the address field in the received frames with a fixed address corresponding to the pattern of said send authorization and generates upon equal addresses a control signal either to a first abort generator or a second abort gen-erator depending on the logic signal state of a second input.          The first abort generator transmits, when activated, an abort word within the frame to the bus.  The second abort generator transmits, when activated, an abortion signal word within the frame towards the terminal.  A flag detection circuit detects the incoming data flow and transmits, for each received, complete flag signal pattern, a control signal to the address comparison circuit to start said comparison.

Abstract: ABSTRACT OF THE DISCLOSURE        A slide fastener stringer includes a row of helically coiled or zig-zag coupling elements of theremoplastic synthetic resin with a reinforcing core extending longi-tudinally therethrough.  The coupling elements are se-cured to one surface of a stringer tape by sewing threads having portions running across and over upper legs of the coupling elements.  Some of the coupling elements are cut off to provide an element-free space on the stringer tape.          A terminal or endmost complete coupling element disposed adjacent to the element-free space has a free-ended connecting portion remote from a longitudinal edge of the stringer tape.  To form an end of the slide fastener stringer, the free-ended connecting end portion of the terminal coupling element is fused to the stringer tape, and at the same time, the upper leg of the terminal coupling element is heated and pressed toward the stringer tape.  A device for forming such a stringer end includes a stringer rest for supporting the end of the stringer, and a heating presser having a first surface for heating and pressing the free-ended connecting portion of the terminal coupling element against the stringer tape and a second surface for heating and pressing the upper leg of the terminal coupling element toward the stringer tape.  The first surface projects beyond the second surface toward the stringer rest.
